As answered by people managing Kanmail and ClientForms.app.
Kanmail's answer
Kanmail transforms your email inbox into a kanban board, letting you drag and drop emails between columns to organize workflows visually. It combines all your email accounts (Gmail, Outlook, etc.) into one unified view while keeping your data private on your device. You pay once and own it forever with no subscriptions.
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
Kanmail's answer
Kanmail offers a visual kanban approach that helps you actually manage email as tasks rather than just reading messages in a list. Unlike competitors, it combines multiple accounts in custom workflow views while keeping all your data local and private. It's a one-time purchase with no subscription fees or cloud dependencies.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.
Kanmail's answer
Kanmail's primary audience includes professionals who manage multiple email accounts and need to organize emails as actionable tasks, such as salespeople tracking leads, customer support teams managing tickets, and power users who want efficient, keyboard-driven workflows. It appeals to privacy-conscious users who prefer local data storage and those frustrated with subscription-based email clients.
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
ClientForms.app's answer:
Frontend: Next.js 15 (React 19), Tailwind CSS Backend: Supabase (PostgreSQL, Row-Level Security) Authentication: Clerk Payments: Stripe Hosting: Vercel (Sydney region) Database hosting: Supabase (Australian data residency)
